I'm looking to pickup up a cabinet for my Mesa Walkabout. It's got a real good growl and i want a cab that can hold up to something like that. i'm sure many are good and i was looking at many different types of cabs. two in particular were (a) Fender 8x10 or (b) ampeg 4x12. my question is, what is the difference between 10" and 12" horns. i imagine it's that i gain some more low-end in the 12ers but i'm not sure at all. please help. any answers, educated guesses are welcome. Thank You!
